STORMWATER PERMIT NO. NCS000330 —ZINC MONITORING:
Dear Samar Bou-Ghazale:
`I"his letter is to notify the DWQ Regional Officeothat ATI Allvac Momoe Sl[e leas collected [lie iequesLed
analytical monitoring for zinc from the gAvanized steel stiuc[ures positioned in the drainage area for our
representative outfall. A summary of the 1 t, 2nd and 3Td zinc sampling values are below:
Sample Location Analytical Value Analytical Value Analytical Value
Wt samnlel (2nd camnle) ljrd camnlnl
Finishing Bldg downspout
0.294 mg/L
0.0583 mg/L
0.299 mg/L

0.450 mg/L

0.212 mg/L
Stormwater #02(M) Outfall 1
0.392 mg/L
0.177 mg/L
0.907 mg/L
As we discussed on our phone call, we are not able to identify any trends in the summary of sampling.
Since the 3rd sampling event for our representative outfall showed unusually elevated levels when
compared to historical sampling, we feel these sampling results may have been a lab anomaly. Therefore,
we plan to take a 41h sample and split them with our current lab and a second lab.
Again, we have implemented BMP's to control potential sources of zinc, such as oil and rubber from tire
wear. Our facility roads and parking lots are routinely cleaned and swept by an industrial service provider.
Also, we have routine pieveii[ative inailr[enauce established on our mobile equipment to reduce hydraulic
oil leaks.
Since we do not have zinc in our products as stated in previous letters, Allvac requests to "monitor only"
for zinc to evaluate the effectiveness of our implemented BMP's. In the meantime, we plan to sample
again for zinc and split the analytical work between two laboratories.
Sincerely,
Preston M. Baucom,
